yes I should bleed the brakes to make sure. they don't really feel mushy but you never know. its hard for me to tell my wife to use her brake when doing the downhill bike trails. it works ok when going down long hills. this bike was setup more as a cruiser bike then anything else. the levers are too short for good back wheel braking and I have trouble with enough leverage on the back when going down those slopes since it we cant use the front brakes much to keep the front wheel from sliding.
so what we are planning if we can get the work done is to have 203 on back 180 on front so it does not rub with cooling fin type discs and some 4 piston calipers with 3 or 4 finger levers. that should be plenty for us.
I like the idea of a drag brake but my wife does ok when it is not a emergency. I might be a bit spoiled with the brakes on my other bike they are so responsive compared to this bike. but they have larger pistons then the shimano brakes have. my wife would like that you can message me.
